PLATFORM-SCALE FOUNDATION.

Application filed May 20, 1922. Serial No. 562,374.

platform scales'especially those operating,

substantially in the plane of the roadway surface, my object being the provision of an improved construction by which without materially increasing costs, I am able to do away with certain objections and disadvantages most frequently constituting the main cause of interference with the proper operation of the scale deck and at all times constituting a source of annoyancev and expense.

It is a well known fact that in structures of the present character dirt and debris finding its way into the scale pits through and around the platform or scale deck, collects in the usual construction so rapidly as to necessitate frequent cleaning and quickly interfere with the proper operation of the scales more especially in View of the fact that owing to the usual difficulties in cleaning it is many times neglected.

My invention proposes a construction which at the same time provides for ready and easy cleaning of the pit and uniform effective support of the scale bearings, and consists in the construction and arrangement of parts shown in the accompanying drawing wherein I Figure l is a top plan view of my improved scale pit or foundation,

Figure 2 is a vertical section taken lengthwise thereof substantially on line 2-2 of 5 ure 1, and v Figures 3 and 4 are vertical transverse sections taken respectively on lines 3-3 and k t of Figure 1.

Referring now to these figures my present invention proposes a scale pit or foundation which, as is usual, is of generally rectangular form, with upright side and end Walls 10 and 11 respectively, one of the former of which has an entrance opening 12 at one side and a drain pipe 13 extending from the lower central portion of its opposite side.

Aroundjthe upper inner ed es of the side walls 10 and v11, which are preferably formed of concrete or similar material, 1

preferably partially embed a protecting angle bar 14, the latter being held in place by anchor rods 15 embedded in the walls, so that the walls will thus have additional protection around the edges .of the scale deck or platform which in its normal position' is flush or substantially flush with the 1 upper edges of the walls.

Centrally as well as at the four corners of the spacewithin the walls 10 and 11 and terminating substantially below the upper edges of these walls, are a plurality of upright piers or pedestals 16 upon the upper ends ,of which are disposed bearing supporting plates 17, the latter bein held with their surrounding edges extending slightly beyond the upper ends of thepiers or pedestals, by means of anchor bolts depending into and embedded within the concrete or other similar, material of which the piers or pedestals are formed. lt will be noted by a comparison of Figures 1 and 2 that the bearing supporting piers or pedestals 16 are frusto-coni'cal in form and each thereof is integral with and disposed upon a lower enlarged rectangular foundation block 18 and entirely independent of the base or floor 19 of the scale pit upwardly through which the piers or pedestals project whereby it becomes easier to set and level the piers in the first instance and cracks or breaks in the base of the scale pit cannot affect this setting.

The base or floor 19 of the scale pit in clines downwardly from the end walls 11 toward the center of the pit as will be clear- 1y seen by reference to Figure 2, and as shown in Figures 3 and 4 it is also inc-lined transversely with its lowermost point adjacent to the inner end of the drain pipe 13, the latter of which may be connected ,in practice to a sewer or the like in order that the interior of the pit may be thoroughly drained at all times of water and dirt collectinq within the pit- I It will also be observed by reference to the several figures that adjacent to the con ners thereof and thus adjacent to the upright corner piers or pedestals, the lower adjoining portions of the side and end walls IO-and 11 are recessed or undercut in a downwardlv and gradually deepening manner as indicated at 20 so that the Walls of these recesses parallel the adjacent portions of the side surface, of ..the corner piers or pedestals, leaving ample and uniform spaces around these piers or pedestals at the corner of the scale pit so as to avoid theready collection and retention of dirt and debris at these points and permit of readily and easily Washing out from the corners any such dirt and debris as may collect.

It is'thus obvious that, owing to the independent setting and support of the several bearing-supporting piers or pedestals, the

or pedestals and otherwise might interfere r with proper operationof the scale parts supiorted thereby p l v In view of the spaces around the corner piers or pedestals by virtue of r'ecessing the side andend walls at their adjoining portions, and theinclining' of the floor, or base or the'pit it becomes an easy simple matter to flush out the dirt and debris by the use of a hose from time to time and at much more infrequent intervals than is necessary to clean out the scale pits now proposed and in use. It is also obvious that byvirtue of the drain pipe extending as it does from the scale pitat the lowermost portion of, the

floor or base thereof, water and moisture is carried off at; all times 'and, especi.ally in freezing Weather it is thus prevented from" interfering With the proper operation of the scales. w 1 I I claim: I y p 1. A foundation or pit for platform'sc'ales having side and end Walls and a base and bearing supporting pedestals of frusto conical form extending upwardlyfthr'ou'gh the base at spaced" points and having foundation'supports below and independent ofthe base and rounded dirt shedding; surfaces above the'base,

2'." A foundation or pit forfplatform scales having side and end walls and a base and bearing supporting pedestals o'f frus'to-con lcal form extending upwardly through the base and having foundation supports below and independent-of the base, certain of said piers orpedes'tals being located adjacent to the corners-of the pit, and said side and end Walls having downwardly deepening recesses 60 at their lower adjoining portions forming uniform curved spaces between the same and v the corner piers or pedestals. v have affixed my In testimony whereof I I JOSEPH MAG ADY.
